Our present invention has reference to a clamp for the stretchers of woven wire fences and the like, and our primary object is the provision of a clamp for this purpose in which the employment of nuts and bolts and other elements which are liable to become loose or displaced are entirely dispensed with and wherein the clamping members are so held that the greater the pull of the stretcherthereon will cause the said members to more tightly engage with the woven wire fence arranged therebetween.

A still further object is the provision of a clamp for this purpose in which the stretcher members may be readily and quickly arranged in operative position, yi ldably held from outward movement when in such position and further wherein the chain elements to which the stretcher is attached are removably and adjustably connected with the clamp members to compensate for the different widths of the woven wire clamped between the said mem- I bers.

To the attainment of the foregoing and 5 other objects the improvement resides in the novel construction, combination and operative association of parts, one satisfactory embodiment of which is disclosed by the accompanying drawings.

In the drawings: 4

Figure 1 is a side elevation of our improvement in operative position.

Figure 2 is a face view of the improvement.

Figure 3 is a top plan view thereof.

Figure 4: is a sectional view approximately on the line H of Figure 1.

As disclosed by the drawings the clamp comprises two rolls l-1 of a similar length and diameter. The clamping rolls 1, on their ends are provided with alin ng but eccentrically arranged trunnions 2-2 and 3-3,' respectively. The trunnions 3 may nature of headed studs or may be in thenature of rods that extend entirely throu h. the rolls 1 and have their ends threaded or the engagement of suitable nuts. The trunnions pass through suitable openings in-an upper r late 4 and'a lower plate 5 and the plates are held on the trunnions by nuts which are which will present themselves 'ceives therethrough be in the Serial No. 525,162

screwed on the threaded ends of the said trunnions. To limit the movement of the eccentrically pivoted rolls toward each other, the said rolls have on their ends pins 6, respectively, to contact with one of the edges of the plates 4 and 5. Obviously by swinging the rolls on their trunnions outwardly with re spect to the plates 4, the rolls will be spaced away from each other to permit an insertion of the woven wire fencing 7 therebetween and that the swinging of the rolls toward each other will cause the fencing 7 to be clamped between the rolls.

In order to permi the upper ends of the rolls being further spread away from each other, and to likewise permit of the wo'ven wire 7 being more conveniently arranged between the rolls the plate t is pivotally connected with one of the trunnions 2 and is provided with a bayonet slot 7 to receive the trunnion on the cooperating roll therein, this construction being clearly disclosed by Figure 3 of the drawings What we will term the outer sides or faces of the rolls, that is, the sides closest to the trunnions 2 and 3, are formed with longitudinal ribs 8. The ribs are provided y grooving or cutting away portions of the said outer faces of the roll and each of the ribs 8 has a series of equidistantly spaced round openings 9 therethrough,othe said openings receiving therethrough the hooked ends 10, respectively, of chain members 11 whose ends are connected by a ring 12 and this ring rethe hooked end 13 on the elements 14 of the stretcher (not shown). By this arrangement it will be apparent that the chainsll. wires of different widths can be arranged between the clamping rolls 1 and the proper amount of frictional engagement by the rolls against the said woven wire can be attained.

In order to hold the rolls properly associated when in operative position we secure on the outer face of one of the rolls, adjacent to the top thereof, one end of a coiled compression spring 15, the other end of the said spring being connected-to the spacer element for a pair of spaced plates 16. To the second and outer spacer element of the said can be adjusted so that the wovenforked fulcrum rection,

comprising two I able on the trunmon of one of the comprising two rolls plates there is pivotally secured the forked and offset fulcrum portion 17 of a lever 18. Pivoted in the forked end of the lever there is the body plate of a hook l9, and the said hook is designed to be engaged by a staple member which is fixed .on the outer face of the second roll or the roll that is not provided with the spring 15. The spacer elements for the plates 16 are in the nature of cross sectionally rounded pins, as disclosed by the drawings. By swinging the lever outwardly with respect to the plates 16 the hook 19 may be readily brought to engage with the staple 20 and by swinging the lever in a second dior toward the roll provided with the staple 20 the ofiset end 17 of the lever will draw upon the hook 19 thereby yieldably latching the rolls 1'1. This is an important feature of our invention as by this simple yieldable latching means the clamp is steadled and the rolls are held in parallelism under all conditions and the clamping-rollsare not susceptible to outward movement or disalinement, and the latch also holds the parts constituting the clamp properly positioned and prevents the loosening or rattling of such parts.

It is believed the construction and advantages of our improvement will be understood and appreciatedby those skilled in the art after the foregoing has been carefully read in connection with the accompanying drawings and while we'have illustrated a satis-' of our improved device our features of invention are capable of extended application limited to the and described.

Havin described the invention, we claim: 1. A c amp esigned to be attached "to a stretcher for woven wire fences or the like,

rolls having g eccentrically arranged trunnions extending from the ends thereof, plates. removably fixed on precise details herein shown the ends thereof, plates removably fixed on the trunnions, the upper plate being swingable on the trunnion of one of the rolls and having a bayonet slot to engage with the trunnion of the cooperating 1'0 1, studs on he ends of the roll to contact with the plates 10! limitin the swinging of the rolls toward and away rom each other, a clamp for yieldably holding the rolls in contacting engagement, including a coil pressure spring secured to one of the rolls, spaced plates to which the s ring is connected, a lever havi orked fulcrum portion pivotle g between the plates, a hook portion pivoted in the forked end of the lever, and a staple on the second roll to be engaged'by the in one direction, ribs on the outer or non-contacting faces of the rolls, ing the said faces of the rolls, and each of said ribs having a series of spaced openings therethrough to receive hooks of chains connected with a stretcher.

In testimony whereof we aflix our signa- .tures.
